MTS Series RM100MF 100W Tube Guitar Amp Head

The Randall RM100MF tube amp head is both traditional and modern technology rolled into one amplifier. First you have three independent modular channels that can be loaded with your choice and combination of the available tube preamp modules. Load each channel with a preamp tone that fits only your needs with the ability to expand your arsenal anytime a new tone is needed. Don't purchase an amplifier because you like just the clean or hi-gain tone. Build this Randall MTS amp with your clean, your rhythm, and your hi-gain tone for a complete custom setup. With more than a dozen tube preamps always available, chances are you'll have a hard time picking just three for the RM100MF amp head.

Change and bias your own power tubes
Enjoy the ease of replacing your power tubes anytime you like with Randall's very user friendly power tube bias section found on each MTS amplifier. If a tube fails, no problem, the Randall amp will kick that tube out of the circuit and a small LED will light by the tube that fails. Simply replace the small protection fuse and tube using a small voltage meter and screwdriver to adjust each individual bias point. If you like experimenting with different tube types, the Randall MTS amp head bias section allows you to pop-in and bias a new set of tubes in just a few minutes.

MIDI channel switching capability
Connect your Randall RM100MF amp head to any MIDI capable effects processor and program individual effects to each channel. With the MIDI in/thru jacks simply select your channel and external effect using the included RF3 MIDI footswitch, press and hold the channel switch button on the head for 2 seconds and hit the store button of the effects processor to save the preset. The included footswitch will then select both the Randall RM100MF channel and effect you want at the same time.
